Proof-of-Concept Windows File Browser
Runs an installer for final script. The main script allows you to hide and open up to 5 folders with unique passwords. This uses the basic hide folder function. The main interface is also protected by a unique password. A setup file with user data is automatically generated. Has a two-stage virulent element that can be toggled - if enabled ; stage 1 activates with repeated failed authentication then stage 2 activates upon hypothetical hate detection. A lost drive feature that displays owner contact information and a rudimentary 2 step verification system are present on welcome interface.
Should run on most commonly available Windows versions.

Arduino Smart Lights
A circuit that automatically toggles a room light when a person enters or leaves a room by using a LASER tripwire. The room light is programed to automatically turn off after a preset time (default : 2 hrs), and turn back on after another preset time (default : 3 secs), and stay on for a preset time (default : 10 mins), to allow time for the user to manually reset an internal timer by commanding the light to turn on via an IR remote, this acts as a warning before the light is automatically switched off by an internal timer. A push-button switch to temporarily disable the LASER can be placed near the tripwire to prevent unwanted toggling of the light if there is more than 1 person. This limitation can be overcome using a second tripwire to calculate direction of movement, but this requires software changes and more hardware, and also increases complexity and power draw. Functions can be manually controlled, including toggling light and LASER via IR remote.
Most hardware components used are easily accessible (a modified LASER-pointer can be used). Infra-Red or Ultra-Sonic sensors can be an upgrade but the hardware (sensors) are relatively harder to find.
This setup can be easily expanded to work on up to 2 lights.

Arduino GPS Clock
An accurate digital clock that uses GPS signal to re-calibrate its time to UTC+05:30, twice a month. If the clock is unable to synchronise after 6 minutes, the attempt is aborted and a retry will be made 2 days later. A precise on-board temperature compensated Real-Time Clock is used for timekeeping (adjusted by GPS for greater accuracy, if synchronisation is achieved). This sketch has power saving optimizations.

Arduino Bluetooth Alarm Clock
A digital clock with a precise on-board temperature compensated Real-Time Clock (RTC) used for timekeeping. An Android app enables communication via Bluetooth and allows interacting with the alarm functions, and also reading ambient temperature in Celsius as well as other functions like adjusting the time, screen brightness and fine tuning or toggling other options like automatic screen dimming. Pre-set values within the sketch can be changed for even finer control. Rechargeable batteries can be connected to form an Uninterruptible Power Supply.
